Fatented June 20, 1933 UNI-TED STATES PATENT OFFICE VERTREES YOUNG AND WALTER C. GEORGE, OF ST. LOUIS, MISSOURI, ASSIGNORS TO ROBERT GAYLORD, INCORPORATED, OF ST. LOUIS, MISSOURI, A CORPORATION OF MISSOURI PACKING CASE Application filed November 8, 1932. Serial No. 340,936.

Our invention relates to packing cases and particularly to packing cases formed of fibre board such as are adapted for use in packing meat and similar purposes.

The principal object of our invention is to provide improved sealing means for fastening the lid or cover of the case in closed position. Other objects of our invention are to increase the resistance of the case to crushing strain and to provide a case which may be easily handled.

In the accompanying drawings which illustrate a packing case made in accordance wlth our invention, Fig. 1 is a perspective view; Fig. 2 is a vertical cross section. the cover being shown in raised position; Fig. 3 1s an enlarged sectional view, showing the sealing means; Fig. 4 is a View similar to Fig. 3 but showing the head of the metal seal bent outwardly, Fig. 5 is an end elevation of one cornor of the case, but showing the use of a longer seal; Fig. 6 is a view similar to Fig. 3, but showing a modified form of sealing means, Figures 7 and 8 are perspective views of the two clips used in the modification shown in Fig. 6; Fig. 9 is a crosssectional View showing a further modificat on; F g. 10 is an enlarged sectional detail view; Flg. 11 is a top view, partly in plan and partly in section taken on the line 1111 of Fig. 9; Fig. 12 is an enlarged elevation of a portion of the front wall looking at the inner side; Fig. 13 is a view of the blank for forming a modified form of cleat; and Fig. 14 1s a sectional view of the cleat formed from the blank shown in Fig. 13.

The case, which is preferably made of sohd fibre board, comprises front and rear walls 1 and 2, respectively, end walls 8, a top 4, and a bottom 5. The front and rear walls and bottom are formed integral and the top is preferably integral with the rear wall, as

shown, so as to provide a hinged lid. The

lid or cover may, however, be made separate from the side walls so as to be completely removable from the case. The front and rear walls and bottom are secured to the end walls by means of flaps 6, through which pass staples 7 or for similar fastening means. As shown in the drawings, the flaps 6 are carcleats are spaced from the walls by fillers 9 so as to provide slots for the reception of flanges 10 on the cover 4.

In order to secure the cover in position, We provide one or more metal fastening clips, each comprising a barbed tang 11 and a T- head 12. The barbs on the tang extend upwardly to prevent the withdrawal of the tang after it has been forced into position. While we have shown the barbs as projecting from what may be termed the inner side of the tang so that they will engage with the side wall of the case, they may project from the opposite side so as to engage with the filler. As shown in Figures =1 to 5, inclusive, slits 13 are formed at the junction of the flanges 10 and the top. These slits are of such length as to permit the passage of the tang of the clip but to prevent the passage of its head.

In using the sealing device, the lid is first closed and then the shanks of the fastening strips are passed down through the slits 13 and forced between the side wall of the ease and the filler. The barbs prevent the fastening strip from being pulled out so that the lid is securely firmly in position. The head may be either bent inwardly, as shown in Fig. 8, or outwardly, as shown in Fig. 4, and the bending may be done either before or after the insertion of the clip. To open the case it is necessary to remove the head by breaking or cutting it from the tang. To facilitate this operation and to prevent the formation of sharp corners on the remaining tang, we prefer to form notches at the junction of the head and tang, as shown in Fig. 8.

l/Vhen the length of the tang is less than the widths of the cleat, the tang cannot be withdrawn after the head is removed androsealing is thus prevented. In case it is desired to reseal the case after it has been opened, clips are used, the tangs of which are somewhat longer than the width of the cleats, so that the ends will project, as shown in Fig. 5. After the removal of the heads, these projecting ends may be engaged by a suitable tool and withdrawn as the barbs will not prevent the movement of the tangs in a downward direction.

In Fig. 6, we have shown a modification in which the slits for the passage of the tang of the fastening clip are not formed in the lid but in an auxiliary clip movable with the lid. This auxiliary clip, shown in detail in Fig. 7', comprises inner and outer plates 15 and 16, respectively, and a connectin web 17 in the latter of which is formed a s it 18 for the passage of the tang 11. Formed on the plate 15 are downwardly projecting barbs for engagement with the flange 10.

. In using the form of fastening illustrated in Fig. 6, the auxiliary clip is placed astride the 11 per edge of the cleat before the lid is close When the lid is closed, the flange 10 enga es with the barbs on the auxiliary clip so t at the lid cannot beraised without. withdrawing the auxiliary clip along with it. The main clip is now inserted as previously described except that its tang is passed through the slit 18 in the auxiliary clip instead of through the lid itself. In this construction the tang enters between the cleat and the filler instead of between the filler and the side wall. The barbs as shown engage with the filler. They may, however, project from the opposite side so as to engage with the cleat, as the same result is secured in either way.

' It is to be noted that in our construction, the upper edge of the end wall, which may be made of any desired thickness, abuts directly against the cover without any intervening bend, thus adding to the resistance of the case to crushing strain. The up er edge of the front wall is, however, pre erably provided with an inwardly projecting flap 19 to overlap the cover, and so provide a better 'oint with the latter. This fla 19 may, however, be omitted in case the flange and the front edge of the cover is made to extend the entire length of the case.

In addition to forming part of the fastening means for the lid, the cleats on the ends 3 provide handles by means of which the case may be conveniently lifted. If heavy fibre board is used for the cleats and filler to provide an effective handle, difiiculty may be encountered in inserting the staples 7 through the three sheets of material. In

order to provide a handle of suflicient thickness without the use of unduly heavy material, we may use the construction shown in Figs. 13 and 14 in which a cleat 8 and a filler 9' are formed integral, the filler being folded to overla the cleat. As the fibre board is quite sti the fold will not be perfectly flat but will assume the form of a more or less open loop, as shown inFig. 14, thus substantially increasing the thickness .of the handle..

In Figs. 9 to 12, we have shown a modification in which means is provided for strengthening the front and rear walls of the case at theirmiddle points and at the same time, obviating the use of a projecting cleat on the outer face of the front wall. In this construction an opening21 is formed between the front wall and the flap 19 -to permit the passage of the flange 10 on the front edge of the cover. Positioned against the inner face of the front wall is a sheet of fibre board 22, having formed in its upper end a recess 23 for the reception of the flap 10 on the front edge of the cover. Over the sheet 22 is placed a sheet 24 and both sheets are secured in position by staples or by any other suitable means. The sheets 22 and 24 perform the same function as the cleat and filler heretofore described and at the same time form a vertical strut or brace extending between the bottom and cover at the center of the length of the case. A strut or brace 25 is secured to center of the inner face of the rear wall 2. This strut may be formed of a single heavy sheet of fibre board.
